ABSTRACT:
The apparatus of the present invention may comprise a housing or other stationary member which may have a chamber therein. A drive member is disposed in the chamber for movement therein. An elongate torque transmission member is rotatably mounted in the housing so as to extend into the chamber toward the drive member. Means are provided to prevent the torque transmission member from moving longitudinally with respect to the housing. An annular connector is disposed between the torque transmission member and the drive member. The connector is connected to the torque transmission member for longitudinal but non-rotating relative movement and threadedly connected to the drive member. Thus the connector can be moved longitudinally along the torque transmission member during normal or automatic operation of the actuator. However, upon rotation of the torque transmission member, with the connector abutting a suitable stop member, the drive member may be caused to move relative to the torque transmission member and the connector.
